It's been 12 months since the last change, more than 8K miles and it appears that the 5W20 performed well. Si still appears high but is trending in the right direction; I believe it's the sealants not the air filter.

Refilled with more of the same.

Looks great! Break in metal appear to be out of the system for the most part now. It appears you could extend it out if you wanted to, but 12 month OCI look to acceptable for your use case.
 
Metals look alright. 2.5 tbn is technically still good but keeping it 3 or higher is healthy. Maybe settle on 7k. What oil went back in.
 
Good run! Thanks for sharing. Did you intend to double your mileage for this last sample at 10k miles?

Not intentionally. This is my son’s car and he’s in college. I wanted to maintain 5k OCIs for another fill or two, but he’s been coming home for visits less this year, and life gets busy, we all know how it can be. But this 8k or 12 months seems like a good interval to stick with.

Understood, I think you're right. Convenience & sample results look good so why not right.
 
Have you considered removing the lower oil pan to inspect for any excessive RTV on the pickup? That is a known issue on these engines and could save you from trouble down the road.

I have read about the RTV issue and watched a few videos, read a few threads about owners removing the oil pan to search for RTV in the pickup and such. Most of the time very little was found. I'm not saying the issue does not exist but simply hoping it affects very few cars, and not mine. 🤞
 
Yeah I wouldn't change a thing. The differences are interesting between the 2 oil changes both with Pennzoil Platinum. Half as much moly, 1000 ppm of Calcium. Your son went double the mileage but Iron only went up 2 PPM.
 
I'll have to show my son this report. He bought a new 23 GR86 and is so freaked out by the perceived engine issues he's been running 3500 mile OCI.
CarlB is correct, a shorter OCI will have no effect on the reported engine issues. Although there's been a class action lawsuit filed a couple of months ago, a search for the RTV problem in this engine yields only a handful of videos, and IIRC, only one or two where there seemed to be excessive RTV in the oil pickup. I'm hoping that normal (non-track) driving will allow this engine to age gracefully. :cool:

Interesting how thin the factory fill was with all that moly. 5w-20 seems good choice in warmer Florida.............when it's warm.

I wouldn't worry too much about the RTV issue. If it's a major problem for this engine, it'll probably spin a rod bearing within the warranty period. Not to mention, in order to check for RTV in the pickup, you have to remove the oil pan, then reseal it with... more RTV.

I believe that the rod bearings on these engines have tin-based overlays. The 1-2 ppm tin is completely normal for these engines during break-in. 0 ppm tin over 8k miles on the latest UOA suggests a low wear rate.

The issue has been oil pressure dropping from lateral g-force. Toyota has denied a few warranty claims until roasted on social media. The aftermarket scene has been testing a lot of changes to the pickup and pan to address it.
